 (NRHP Bulletin 40)

Unlike the Battlefield and Core Area boundaries, which are based only upon the interpretation of historic events (historic landscape), Area of Integrity boundaries, also referred to as Potential National Register (POTNR) boundaries, are based on an assessment of the current landscape's integrity (modern landscape) using the guidelines outlined in National Register Bulletin 40.The boundaries drawn around these areas encompass lands that retain their historic integrity and either are already preserved or could be preserved in the future.These boundaries must fall fully within the Battlefield Boundary.
